OIL-DISCHARGE JET.

Application filed September 2, 1921.

To all "Hi/2.0772 it may cmwcm.

lie it known that we, l-lmvur l limeli- BURN, a citizen of the UnitedStates, residing at Breckenridge, in the county of Ste )hcns and Stateof Texas, and llnm. I1.

Me ILLEN, a citizen of the United States,

residing at Ranger, in the county of Eastland and State of Texas, haveinvented cer tain new and useful Improvements in ()il- Discharge Jets,of which the following is a specification.

()ur invention relates to gas jets for lifting oil out of wells bynatural gas; and the object is to provide a simple jet which will beself acting to lift oil out of wells by utilizing the pressure ofnatural gas and another object is to make the gas engage the oil in adirection approximating the direction of the oil which is beingdischarged so that the low of oil will not be impeded but pushedupwardly and saving the force of the momentum of the oil. Other objectsand advantages will be fully explained in the following description andthe invention will be more particularly pointed out in the claim.

Reference is had to the accompanying drawings which form a part of thisapplication.

Fig. 1 is a side elevation of the jet, showing how a sleeve and adischarge pipe. are connected to the lower end of the jet. Fig. 2 is avertical section of the jet. Fig. 3 is a plan view of the jet. Fig. 4 isa bottom plan view of the same.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The jet is interposed between two sections of a dischar e pipe. The jethas body 9 and is threaded interiorly at the upper end 1 to receive thelower end of a discharge pipe section 10. The lower end is threaded at 2for receiving the upper end of a discharge pipe section 3. The section 3may be forty feet more or less and has perforations 12 near the lowerend for admission of oil from the oil producing sands. The jet has anopening 8 therethrough to form a passage for oil from the section belowto the section The gas is let into the oil Serial No. 498,117.

above. The oil flows up through the discharge pipe and the jet 9. Inorder to aid and increase the flow of oil/and to make the oil flow,provision is made for utilizing the pressure of natural gas to force theoil upwardly. A sleeve (5 is screwed on the lower end of the jet 5) andextended down any suitable distance to form an annular chamber 7 aboutthe pipe section 3 for collecting and concentrating the gas pressure.passage through ducts 5 in the jet 9 at a small angle to the directionof the flow of oil so that the gas will be going as nearly as possiblein the direction of the oil flow so that the gas will not interrupt butaid the flow of oil.

In operation, the oil flows up pipe 3 and through the opening 8. Thenatural gas rises up in the annular space about the pipe 3 within thesleeve 6 and then escapes through the ducts 5 into the oil passage andso lifts the oil on through the discharge pipe.

This method is preferable to the methods of introducing air or steam orgas down into the wells for ejecting oil because in this method, thelift is always upwardly and none of the gas presses downwardly whereassteam or air or gas forced down into a well tends to force the oil backinto the reducing sands. The efiiciency of the jet ierein deseribed hasbeen fully demonstrated thoroughly in actual service.

The jet is threaded exteriorly at 4 for convenience in removing the jetin case the socket '1 should become plugged so that a spear cannot enterthe socket for removal. The socket 1 is threaded interiorly to receivethe pipe section 10. What we claim, is,

A "et for lifting oil from wells by natural gas through a discharge pipeconsisting of a body member consisting of a single casting having anunobstructed passage for oil therethrough and adapted to be connected tosections of a discharge pipe above and below said body and having thelower end thereof cylindrically enlarged and having relatively longinclined gas ducts from the lower end through said enlarged portion andtormiabout tho oi] disulmrgo pipe for projecting noting in said oilpossago for directing gas gas through said ducts.
